Wilin Rosario battles cramps in bullpen session, still expected back for Rockies' final series

Colorado Rockies catcher Wilin Rosario is still trying to get back out on the field before the 2013 regular season is out, despite suffering from cramps during a bullpen session on Wednesday night. Rosario has been trying to come back from a calf strain that has kept him out since September 17th, with Ian McCue of MLB.com reporting that the young catcher had to come out of the session when he started experiencing the cramps. Manager Walt Weiss was still keen to leave the door open for a return during their final series. "He started to cramp up a little bit and had to step away from that bullpen session," Weiss said. "I don't know if I'd call it a setback, but I think once he felt a little cramping, we got cautious...It's not a sure thing, but I still have a feeling he's going to play sometime in L.A." Initially the Rockies had just expected Rosario to miss 'a couple of days' but it has now been over a week since the 24-year-old appeared in a game. The cramps are presumably a very minor concern if Weiss is even thinking about starting Rosario at such a late stage of the season. The team has an off-day on Thursday and will head to Los Angeles to face the NL East champion Dodgers for a final three-game series. The injury has seen Jordan Pacheco splitting time with Yorvit Torrealba behind the plate, doubling Pacheco's appearances at the position this season from four to eight already. The 27-year-old has played catcher extremely sporadically over his three-year career, appearing there just 19 times with only 14 starts. The Rockies have moved him all over the diamond since he came up; he played first, second, third and catcher in his debut season of 2011, then was predominantly a third baseman last year, with 80 starts there, before being used mostly at first in 2013. Pacheco has actually made over three-quarters of his minor league starts at catcher (303 games out of 391) but has not been able to hold down a job there in the majors as he has really become Colorado's emergency catcher behind Rosario and Torrealba.
